Application tiled February 4,1967.- Serial No. 355,707,

'To all 'whom it may concern;

Be it known that I, WILLIAM S. ScHRoaDEn, a citizen of the United States, and a resident of the city'oi Chicago, county of Cook,l and State of Illinois, have invented certain new and useful Improvements in Car-Couplings, of which the following is a specification.

My invention relates to car couplings of the Janney type, wherein a horizontally disposed locking bar is operated by a vertically movable lifting pin, and has for its objects to provide, nist, means whereby the lifting pin, when raised to lift the llocking bar to the unlocked position, will be automatically forced either to engage on the lock-set when released or to follow to some degree the coupling hook tail in its opening movement when said lifting pin is operated as a coupling hook opener; and, secondly, means whereby said lifting pin will, when the coupling hook moves towards the closed position, be automatically shifted so as to drop free from the lockset when the parts are released by the coupling hook as the latter reaches its closed position. These objects I accomplish in the manner and by the means hereinafter described and claimed, reference being had to the accompanying drawings, in which:

Figure 1 is a longitudinal sectional view, showing the parts in the locked position. Fig. 2 is a similar view, showing the parts in the lock-setposition. Fig. 2a shows the parts at the end of the opening movement, the lifting chain taut. Fig. 3 is a similar view, showing the coupling hook in the open position, and the locking-means supported thereby. Fig. 4 is a pei-sped tive view of the locking means detached, in the position shown in Fig. 1, looking from the opposite side. Fig. 5 is a bottom plan view of the locking bar. Fig. 6 is a horizontal section taken through the draw-head and draw-bar, the coupling hook and locking bar being shown in full lines. Fig. 7 is a vertical transverse section on the line 7-7, Fig. 6, the lifting pin being shown in full lines.

Similar numerals of reference denote corresponding parts in the several views.

In the said drawings the reference numeral-ladenotes the draw-bar of the coupling, and 2 the drawhead o the .lanney type, having pivoted therein at 3 the-usual coupling hook 4, said coupling hook having its tail portion extended at 5 to form a support for the locking means during the entire opening movement of the coupling hook, a construction well known inthe art.

Extending longitudinally in the draw-bar 1 is the locking bar 6, the same having its enlarged forward end or head 7 disposed in the path of travel o the coupling hook tail to lock the latter. Said locking pin may be pivotally connected to the draw-bar at its rear end in any suitable manner,- the preferred means shown consisting of pintles 8 vformed on the rear end of said locking bar that detachably engage in a bearing 9 formed in the drawhbar, said connection permitting a free vertical movement to the head 7 of said locking bar.

Located and vertically movable in the upper and lower apertures l0 and l1 in the draw-head 2 is thel lifting pin 12, the same being operated .in the usual manner by means of a chain 13 connecting it with a lever 14 pivoted to the car body. Said lifting pin is recessed on one side at 15 to loosely receive the ront end of theY locking bar 6, the upper and lower surfaces o said recess being formed with substantially parallel y inclines 16 and 17 that coperate, respectively, with similar inclines 18 and 19 formed on the locking bar 6 in a manner hereinafter to be described, the incline 18 being formed on top of the head 7 of said locking bar, while the incline-19 is formed on the underside of said locking bar. The lower end of said lifting pin 12 is curved forward'into a lip 20 provided with a cam 21 that serves the double function of acting as a coupling hook opener, as will be hereinafter described, and, in connection with a seat 22 formed in the draw-head, as a lock-set for said lifting pin. The lower incline 17 on said lifting pin is extended into a forwardly projecting finger 23, which is provided with a beveled or inclined side face 24: adapted to be engaged by the coupling hook ltail under the Opening movement of the latter which tends to force said lifting pin from engagement with the lock-set seat 2 1.

The tail of the coupling hook 4 is extended at 5 to form a ,support for the locking means during the entire opening movement of said coupling hook, and hasa vertical face 26, that abuts against the locking bar 6 when in the locked position, adapted to lie parallel with the side face of the head 7 of said locking bar 6. The upper surface oi said coupling hook tail is inclined upwardly at 27 from the face 26 thereoftowards its'rear end, and. its lower surface is similarly inclined at 28, as best seen in Fig. 3. p I

From the above description the operation of my improved construction will be understood as follows: With the parts in the position shown in Fig. 1, the coupling hook is shown locked by the engagement withthe face 26 thereof of the head 7-oi the locking bar 6, the

lifting pin -12 being shown in its lowermost position.`

locking position, shown in Fig. 2,'said inclines coper- `liar to the u ating to force the lower end of the lifting pin forward so that, when released'7 its lower forwardly curved lip 20 will drop ont'- the seat 22 in the draw-head and thus retain the parts in the lock-set position. Should it be desired to throw the coupling hook open, the lifting pin 12 is raised further, and as the cam 2l on its lip 2() engages the incline 2S on the underside of the coupling hook tail said coupling hook will be forced towards the on the coupling hook tail with the front end of the locklng bar, which causes the inclincs 16 and 18 on the lifting pin and locking bar, respectivcly,`to engage, which in turn shifts the lower end of said lifting pin 12 to the rear. Now, as the coupling hook tail moves rtowards the closed position, the front end of the locking bar 6 will slide down said incline 27, and the' 'cooperating inclines 16 and 18 on the lifting pin 12 and locking bar 6 will cause the lower end of said' lifting pin to move still further to the rear, so that, when said locking bar and lifting pin are released to drop to the locking position, which occurs when the coupling hook tail reaches its closed position, all danger of said lifting pin engaging with thelock-sct seat 22 is obviated.

lt will be observed that while the foi-it ardly projecting finger 23 will lie in the path of ltravel of the coupling hook-tail when the parts are inthe lock-set position, so that the coupling hook tail, when moving towards the open position, will kick said liiting pin off the lock-set; still I prefer to employ the cooperating inclin 16 and 18 for this purpose. 4

By referring more particularly to Figf it will be observed that the underside or incline 28 of the coupling hook tail is somewhat convened, so that, when contacted with by the lip 20 of the'lifting pin 12 in throwing open the coupling,` hook, the angle of contact between said incline 28 and'salid lip 20 will increase gradcally as the coupling hook opens, thereby more surely effecting the complete opening of said coupling hook.
